    it acts like normal when i put a cd in, except there's no audio at all. the volume buttons do nothing.
    i can still hear the beeps when i pause or skip a track, the minutes and seconds show up along with the track number, and the cd is rotating, but the music just never plays. it does this for every cd i own, and i tried switching out the batteries and using different headphones but im pretty confident theres a problem with the walkman itself. is there a way i can fix this?
    the back says it was manufactured may 2001

    Looks like this Discman does not have Line-out, so there is not much else you can test without opening her up! The good news - Service Manual is available for free here:

    Since you hear BEEPS, the headphone jack is solid, and the line between h/p amp (IC701) is open, 220uF/4V coupling capacitors C718 and C719 still OK, and IC701 transfers the signal from BEEP(17) to OUT-R(8) and OUT-L(6). Take a close look around IC701 and IC702 (Volume), since both L and R channels are dead check first for something like Q703 which kills both channels when going Bad. But most probably you will see the problem right away, like leaking bypass electrolytic or a piece of dirt. Check the Flex-Board going into the lid, sometimes they crack
